In the Sequels, however, we are told the force likes to balance itself out. So to balance Snoke and Kylo we have Rey. But Rey wasn’t a Jedi before. The force just randomly called to her?

This sets up an interesting message: don’t work hard. Just hope you will be lucky and suddenly become the one gifted person in the galaxy. All because someone else worked really hard on the other side and we need balance.

That’s a very strange interpretation of those films. Do you remember how TLJ ended?

All the ending shows is one boy suddenly getting force powers. We have little context how he got these powers, so while I suppose its possible he has been spending his life training to be able to use the force, it’s more likely he just randomly got powers with ease. The death of Luke called upon the broom boy (the only one we see) to take his place in the light side.
